Nitta Yoshiaki

Who They Were

Nitta Yoshiaki (新田義顕, にった よしあき) was a samurai of the late Kamakura period, born in 1318 and dead by 1338. He was a son of Nitta Yoshisada, one of the most consequential military commanders of his age, and he belonged to the Nitta clan, a branch of the Minamoto line that had settled in the Kantō plain. His career was short even by the standards of a violent era: he died in his early twenties, fighting for Emperor Go-Daigo against the Ashikaga.

The world he was born into was already coming apart. The Kamakura shogunate, the military government that had ruled Japan from the Kantō since 1185, was losing its grip on the provinces and on the imperial court it claimed to police. Yoshiaki's father would help pull it down.

Life and Career

Yoshiaki was born in 1318, in the second year of the Bunpō era (文保, ぶんぽう). His father, Nitta Yoshisada, was a Kantō lord whose family had long been overshadowed by the Hōjō, the clan that dominated the Kamakura shogunate. In 1333 Yoshisada marched on Kamakura and destroyed the shogunate, an act that made him one of the central figures of the Kenmu Restoration — the brief attempt by Emperor Go-Daigo to restore direct imperial rule.

Yoshiaki came of age inside that conflict. When the restoration collapsed and the Ashikaga clan under Ashikaga Takauji turned against Go-Daigo, the Nitta became the emperor's most reliable sword arm. Yoshiaki fought in his father's campaigns through the 1330s, and by the middle of the decade he had risen to command in his own right.

His defining engagement was the defence of Kanagasaki, a fortress held for the emperor's cause. Yoshiaki was one of the chief generals of the garrison. The Ashikaga attacked in force, and the fortress fell. Yoshiaki was killed in the fighting. Prince Tsunenaga, an imperial prince who had been at Kanagasaki, was taken captive. The year was 1337, though Yoshiaki's recorded life span runs to 1338.

Why They Matter

Yoshiaki matters less for what he built than for what his death marks. Kanagasaki was one of the moments when the Kenmu Restoration's military position in the north finally broke. The emperor's cause did not recover from the loss of commanders like him.

He also matters as a case study in how the Nitta clan worked. Yoshisada staked everything on Go-Daigo, and his sons were spent in the same gamble. Yoshiaki died young, in his father's war, on his father's side. The Nitta were destroyed as a political force within a generation.

And he matters because the Ashikaga victory at Kanagasaki helped clear the way for the Ashikaga shogunate, the government that would rule Japan from 1336 until 1573. The world Yoshiaki died trying to prevent is the world that followed him.

The Name in Japanese

The full name is written 新田義顕. It is read にった よしあき in kana, and romanised as Nitta Yoshiaki. The family name comes first, as is standard in Japanese.

新田 (にった, Nitta) — the clan name, two characters:

• 新 (にっ, nit-) — "new." In this compound it takes a shortened, clipped reading rather than its standalone form あたらしい or あらた.
• 田 (た, ta) — "rice field," "paddy." One of the most common elements in Japanese place names and surnames, since rice land was the basis of wealth and lordship.

Together 新田 means "new rice field," and it began as exactly that: a place name in the Kantō region. The clan took the name from the land it held.

義顕 (よしあき, Yoshiaki) — the given name, two characters:

• 義 (よし, yoshi) — "righteousness," "justice," "duty." This character was enormously popular in warrior names of the period, and it was frequently granted by a superior as a mark of favour. Note that 義 can also be read ぎ (gi) in compounds, but in this name it is よし.
• 顕 (あき, aki) — "to appear," "to be manifest," "to make clear." A less common name element than 義, which makes the combination distinctive.

The pattern here is worth noticing for anyone reading pre-modern Japanese names: a single kanji can carry several readings depending on context, and given names in particular were read in ways that no dictionary will predict. 義 is よし here, not ぎ. 顕 is あき here, not けん. The kana reading にった よしあき is the only reliable guide.

Legacy

Yoshiaki left no lasting institution and no body of writing. What survives is his place in the record of the Nitta clan's war: a son of Nitta Yoshisada, a commander at Kanagasaki, killed there when the fortress fell and Prince Tsunenaga was captured.

His name persists mainly through his father. Yoshisada is the figure histories dwell on — the man who burned Kamakura in 1333 — and Yoshiaki appears in that story as one of the sons who paid for it. The Nitta clan's stand for Emperor Go-Daigo became, in later centuries, a favourite subject for those who wanted to argue that loyalty to the throne outranked loyalty to whatever military government happened to be in power. Yoshiaki's death at Kanagasaki belongs to that tradition.

For a reader of Japanese, his name is also a small lesson in how the language handles personal names: place-name surnames, kanji with multiple possible readings, and a kana gloss that has to be memorised rather than deduced.
